Google Earth; rubatsiro rwakaonekwa rwevashandi vemapepa

Google Earth, kunze kwekuve chimbo chekuvaraidza kwevanhu vose, yakavawo rubatsiro rwekuona mapepa ekudhirota, zvose kuratidza zviitiko uye kutarisa kuti basa riri kuitwa riri rakafanana; kwete kutaura sechidzidzo chechikoro che geography kana geody classes.

Mune ino kesi ini ndiri kuenda kunobatsira Manifold GIS kuvaka maquadrants neGoogle Earth kuongorora mhedzisiro, kushandisa mukana wechiitwa chatakatanga pamwe chete naCristian Mejía, muongorori anobva kuSucre akabatsirwa neruzivo. Pamwechete, tinofanirwa kudzika nzvimbo yatinozoshandira, kana iri Bolivia, iri pakati penzvimbo 19, 20 ne21; uye latitude 8 ne24 degrees, kumaodzanyemba kwenyika. Zvese izvi zvinogona kudhonzwa kubva kuGoogle Earth nekutarisa kuri nyore, kuchinja sarudzo kuti uzvione muUTM kuti uone zvakajeka nzvimbo uye munzvimbo dzenyika kuti uone maitiro uye urefu.

1. Iyo quadrant yenzvimbo nhatu dzekufarira.

MuMangwanda inoitwa ne Wona> gridhi

Ipapo isu tinoratidza kuti tinotarisira quadrant inoenda kubva kuhurefu -54 kusvika -72, haina kunaka nekuti iri kumadokero kwenyika. Uye iyo latitude yatinosarudza pakati -8 na -24, ivo vachiri vasina kunaka nekuda kwekuve pazasi peequator.

Isuwo tinoratidza kuti tinoda kugovana sei; iyo yose yakazara 18 (3 6 spindles) muhurefu uye gumi nematanhatu (16 nguva 2 madhigirii) muhushe. Tinoratidza kuti munotitenda tiles panzvimbo pemitsetse yakapusa. Uye ipapo tine nzvimbo nhatu, sezvazviri pamusoro muGoogle Earth,. Kuti tidziedze, tinodzvanya kurudyi uye kutumira kune kml, zvichiita kuti zvioneke zvine musoro zvekuti murabhoritari ye geodesy makore makumi maviri adarika zvainetsa kunzwisisa.

2. Mepu 1: 250,000

Semuenzaniso, tiri kuenda kunoshandira zone 20 nenzira imwecheteyo. Mune ino kesi, iwo 1: 250,000 machira ane chiyero che 1.5 x 1 degree, yakaenzana nekukamura nzvimbo yese kuita 16 x 4 matrix tiles.

Isu tinoratidza kuti iye zvino tinongoda grid iri pakati pehurefu 60 ne66, uye the latitude of 8 to 24; izvo zvinoreva kuti zvikamu zve6 zvichaparadzaniswa muzvikamu zve 1.5 uye maitiro muzvikamu zvedunhu re 1.

Yakaitwa: kutarisa, kurudyi tinya uye kutumira kune kml. Mukutarisa / kureba kutarisa iwe unogona kutarisa kana mitsara ichienderana neGoogle Earth grid.

Kuti uwedzere macentroids, mataira ese anosarudzwa, uye geo-processing function inoiswa, sezvinoonekwa mune inotevera graphic. Izvo hazvidikanwe kugadzira imwe dura, sezvo Manifold inotsigira mhando dzakasiyana dzechinhu mukati mayo, kana iwe uchida kutumira kune imwe, haufanire kana kuvasarudza nekuti ivo vakagadzirwa nesarudzo yakaitwa kuitira kuti chete bvisa / paste.

3. Mepu 1: 100,000

Muchiitiko ichi, hapana chinoshandisa kupfuura kudarika, zvikamu zve 1.5 zvakakamurwa kuita zvikamu zvitatu, saka vanogara 0.50 x 0.50.

4. 1 maps: 50,000

Zvinopera pasina kutaura kuti inotevera dura yakakamurwa kuita zvikamu zve 0.25 x 0.166667, sezvo tiri kuigovanisa kuita 2 x 3 matrix, sekuonekwa mune yekupedzisira mhedzisiro. Kurudyi zvidimbu zvinoratidzwa, mukati mefaira uye pazasi pavo mukati memepu, yakadaro sezvatinotsanangura zuva rimwe.

Uye izvi ndizvo zvaizova muGoogle Earth, tinogona kuzviita kamwechete, pamwe nenharaunda yose, zvisinei nokuti hazvikwanisi nokuti isu tichatoda kuvashandura kuUTM uye izvi zvinoitwa nematanda akaparadzaniswa nenzvimbo.

Zvinonakidza kuti Manifold .map faira rine zvese, zviyero 85 kb uye Google Earth 59 kb.

Pano unogona kukopa iyo faira format .map for GIS Manifold uye .kmz kuGoogle Earth.

Pakupedzisira, kuita izvi pasina Google Earth kwaizoda nguva yakawandisa yekutarisa kusabatika uye kusahadzika kwechikanganiso chingangoitika. Mifananidzo yeGoogle hazvizove yakarurama zvakadaro, asi sechikoro chekudzidzisa chinogona kubatsira zvikuru kusvika pakuita kuti kushandiswa kwaro kwakagadzirisa zvidimbu zvakasiyana siyana kune zvishongo zvehofisi.
